Rated 4 out of 5 stars

Generally works great. Over the last week or two it seems to no longer be able to download VEVO videos so I don't know if they have come up with some kind of block.

This review is for a previous version of the add-on (4.2.6.1-signed). 

Youtube has made some major architectural changes and Vevo videos as well as others can no longer be downloaded. An update is in the works and should be up shortly.
